There is also a secret level in RyS that has ghost Mercs, Krall, Pupae, and Slith - but I won't waste your time with those, since there are very few of them and it's a secret level only. The Skaarj and Brutes appear in the normal levels.

Now the pawns can play all of their usual death animations, too. Another thing to note is that the disintegrating mercs shoot at you after you shoot their heads off. Normal mercs spawn corpses when they die, so nothing happens since the merc corpse doesn't have a shooting function.

Once again, you rock! I will definitely use all these effects for the secret level.

I noticed one more tiny thing, but it's not a big deal. Is there a way to stop the Skaarj from blocking the player during the disintegrating effect? They currently block the player during the death animation, which can be a problem when you are fighting a lot of them and one of them blocks your bullets and/or escape route for a few seconds. As soon as the effects begins, the collision should be disabled.

By the way, this might be a nice mutator later on. Although I don't play coop anymore these days, I imagine this mutator would work with coop servers to reduce demand on the server (with no gibs or bodies around). It also looks pretty cool.
